Hole-Expansion: Sensitivity of Failure Prediction on Plastic Anisotropy Modeling

Hole-Expansion: Sensitivity of Failure Prediction on Plastic Anisotropy Modeling

The influence of yield function parameters on hole-expansion (HE) predictions are investigated for an anisotropic AA6022-T4 aluminum sheet. The HE experiment is performed in a fully-instrumented double-action hydraulic press with a flat-headed punch. Full strain fields are measured by a stereo-type...
